Band and Mode Selection
Tap either end of the B AND switch to select the
desired ham band (160through 6 meters). You can
also go directly to any desired frequency using
direct frequency entry (pg. 15), or recall a
frequency memory (pg. 16).
Tap either end of MOD E to select the operating
mode. Hold ALT to select an alternate mode, if
required. This include CW REV (pg. 30), DATA
REV (pg. 31), AM-S (synchronous detection, pg.
29), and FM +/- (FM repeater split, pg. 29).
Antenna Selection and Matching
ATU (KAT3)
If you have the KAT3 antenna tuner installed, you
can select ANT1 or ANT2 by tapping ANT.
Hold ATU to select AUTO (autotune enabled) or
BYPASS. If the ATU icon is on, the antenna can
be matched for best SWR by tapping ATU TU NE .
ATU settings are saved per-band and per-antenna.
Tapping ATU TUNE a secondtime within 5
seconds of a match attempt will retry using a more
extensive search. This may improvethe match
when using high-SWR or narrow-band loads.
Holding ANT allows names to be assigned to
antennas (e.g., ‘YAGI’).These will be flashed each
time you switch antennas. When editing names,
VFO B selects the character positionto change;
VFO A cycles through available characters. Setting
the first character to “—” disables name display.
RX Antenna (KXV3)
With the KXV3 installed, you can tap R X to select
a receive-only antenna (RX ANT IN). The K3 also
has an RX ANT OUT jack for use with in-line
filters, thePR6 6-m preamp, etc.; see pg. 38.
Sub Receiver Antenna (KRX3)
If the sub receiver is turned on (by tapping SUB ),
its antenna selection can be changed using BSET .
While in BSET,tap AN T to switch between MAIN
(sharingthe main antenna) and AUX (usingthe
sub’s AUX RFinput). For further detailson sub
receiver antennas, see pg. 37 andpg. 40.
Using the VFOs
VFO A is both the main receive andtransmit
frequency, except during SPLIT, in which case
VFO B controlsthe transmit frequency (pg.36).
VFO B also controls the sub receiver (pg. 37).
Tap R ATE to select 10 / 50 Hz per step. The faster
rate can be changed using CONFIG:VFO FST.
The number of counts(or steps) per VFO knobturn
can be changed using CONFIG:VFO CTS.
Tapping R ATE briefly flashes either the 10-Hz or
100-Hz digit to indicate slow or fast tuning.
For 1-Hz steps, tap FI N E ; for wider steps, use
COAR SE (see CONFIG:VFO CRS). When FIN E
is in effect, a 1-Hz digit will appear in the VFO A
display. When COAR SE is in effect, the 10-Hz
digit is not shown.
Tap A B once to copy VFO A’s frequency to
VFO B. Tapping A B a second time within 2
seconds also copies VFO A’s mode, filter, and other
settingsto VFO B.
A / B exchanges VFO A and B andtheir settings.
(Also see CONFIG:VFO B->A.) Pressing REV
exchanges the VFOs for as long as you hold it in.
VFO B and the sub receiver can be set up directly
by holding B SET. While BSET is in effect, all
icons and VFO-related controls applyto VFO B
(andto the sub receiver, if turned on; see pg. 37).
Holding SUB links/unlinksthe VFOs, whether or
not a sub receiver is installedor turned on (pg. 37).
RIT and XIT
The RIT/XIT offset control, at the far right, setsthe
offset for RIT and XI T. The offset is shown on the
VFO B display as you adjust the control.Three
LEDs show whether the offset is 0, (-) or (+).
Tap C LR to zero the RIT/XIT offset. Tapping it a
secondtime restores the offset.
To copy the present RIT offset to VFO A, hold
CLR for 2 seconds. VFO A will be moved to the
new frequency before the offset is zeroed.
If RIT and XIT are both turned off,the RIT
offset can coarse-tune VFO A (CONFIG: VFO
CRS). For example, you can select 5, 9, or 10 kHz
steps in AM mode.
